Poyeretsa madzi m'zimbudzi, kugwiritsa ntchito chotsukira madzi chokha nthawi zambiri sikuthandiza. Polyacrylamide (PAM) ndi polyaluminum chloride (PAC) nthawi zambiri zimagwiritsidwa ntchito pamodzi poyeretsa madzi. Zonsezi zimakhala ndi makhalidwe ndi ntchito zosiyanasiyana. Zimagwiritsidwa ntchito pamodzi kuti zipange zotsatira zabwino zokonzera madzi.
1. Polyaluminum chloride(PAC):
- Ntchito yaikulu ndi yofanana ndi coagulant.
- Imatha kuletsa mphamvu ya tinthu tomwe timapachikidwa m'madzi, zomwe zimapangitsa kuti tinthu timeneti tisonkhane ndikupanga ma flocs akuluakulu, zomwe zimathandiza kuti dothi lisungunuke komanso kusefedwa.
- Yoyenera madzi osiyanasiyana ndipo imathandiza kwambiri pochotsa madontho, utoto ndi zinthu zachilengedwe.
2. Polyacrylamide(PAM):
- Ntchito yaikulu ndi monga flocculant kapena coagulant.
- Zingawonjezere mphamvu ndi kuchuluka kwa floc, zomwe zimapangitsa kuti zikhale zosavuta kupatukana ndi madzi.
- Pali mitundu yosiyanasiyana monga anionic, cationic ndi non-ionic, ndipo mutha kusankha mtundu woyenera malinga ndi zosowa zanu zamadzi.
Zotsatira za kugwiritsa ntchito pamodzi
1. Kuonjezera mphamvu ya kutsekeka kwa madzi: Kugwiritsa ntchito pamodzi kwa PAC ndi PAM kungathandize kwambiri mphamvu ya kutsekeka kwa madzi. Choyamba PAC imachotsa tinthu tomwe timayikidwa m'madzi kuti tipange ma floc oyambirira, ndipo PAM imawonjezeranso mphamvu ndi kuchuluka kwa ma floc kudzera mu kulumikiza ndi kulowetsedwa kwa madzi, zomwe zimapangitsa kuti zikhale zosavuta kukhazikika ndikuchotsa.
2. Kuwongolera magwiridwe antchito a chithandizo: Kugwiritsa ntchito PAC imodzi kapena PAM sikungathandize kwambiri pa chithandizo, koma kuphatikiza ziwirizi kungathandize kwambiri pa ubwino wawo, kupititsa patsogolo magwiridwe antchito a chithandizo, kuchepetsa nthawi yochitira zinthu, kuchepetsa mlingo wa mankhwala, potero kuchepetsa ndalama zochizira.
3. Kukweza ubwino wa madzi: Kugwiritsa ntchito pamodzi kungachotse bwino zinthu zolimba zomwe zapachikidwa, kutayikira kwa madzi ndi zinthu zachilengedwe m'madzi, ndikuwonjezera kuwonekera bwino komanso kuyera kwa madzi otuluka m'madzi.
Malangizo Othandizira Pakugwiritsa Ntchito
1. Kuonjezera motsatizana: Kawirikawiri PAC imawonjezeredwa kaye kuti iyambe kugayika, kenako PAM imawonjezeredwa kuti igwire bwino ntchito, kuti pakhale mgwirizano wabwino pakati pa ziwirizi.
2. Kuwongolera Mlingo: Mlingo wa PAC ndi PAM uyenera kusinthidwa malinga ndi momwe madzi alili komanso momwe mankhwala amafunikira kuti apewe kuwononga ndi zotsatirapo zake zomwe zimachitika chifukwa chogwiritsa ntchito mopitirira muyeso.
3. Kuwunika ubwino wa madzi: Kuwunika ubwino wa madzi kuyenera kuchitika panthawi yogwiritsidwa ntchito, ndipo mlingo wa mankhwala uyenera kusinthidwa nthawi yake kuti zitsimikizire zotsatira za kuchiza ndi ubwino wa madzi otuluka.
Mwachidule, kugwiritsa ntchito pamodzi polyacrylamide ndi polyaluminum chloride kungathandize kwambiri kuti madzi azigwiritsidwa ntchito bwino, koma mlingo ndi njira yogwiritsira ntchito ziyenera kusinthidwa malinga ndi momwe zinthu zilili.
